Competitive Interactions between Apis and Bombus

Between 1998 and 2000, two to three Apis colonies (consisting of 10,000 to 15,000 workers each) were introduced in three places from the beginning of June to the beginning of September (Thomson 2004). Each Apis colony is 2 km away. In the case of natural bumblebee, colonies of western flower thrips are located 10 meters, 500 meters, 1000 meters from each place. There are a total of nine Western flower thrips communities for three distances and three different loci. Western pheasant species are located in the same place every year, but long distance treatment has been changed (Thomson 2004).

Bombus occidentalis occidentalis in the west, Bombus franklini in the Frank, Bombus crotchii in the cloak, and Bombus suckleyi in the cuckoo are in danger of extinction. The International Conservation Union for Nature Conservation (IUCN) Hornet Expert Group is a worldwide network of researchers specializing in the protection of bumblebee bees, these species are valued in the IUCN endangered red list and have the following values . Please note that this petition concerns certain variants of the Western hornet (Bombus occidentalis occidentalis), which is not formally included by the World Protection Confederation. However, analysis of the extent and relative abundance of western thrips by Rich Hatfield, an endangered species protective biologist at the Xerces Society recently shows that the variants meet the endangered criteria of the IUCN Red List.

Like many other bees and bees (Hymenoptera), bumblebee is a social insect. However, unlike the domestic bee Apis mellifera, its nest is composed of hundreds of thousands of people, and some colonies in the tropics may be over 1,000, but usually 50 to 100 people, rarely It does not exceed 500 people. In addition, in general, most bee hives succeed in overwintering and only the queen of newly fertilized Bumblebee can survive the winter. At the beginning of spring every year the young Hornet awakens from hibernation, founded the colony and founded it. The young queen raises their first descendants alone and also becomes hay fever until the first generation can take over the task of the nanny before they can begin to collect nectar.
